Embodiments are directed cook-off mitigation systems. As assembled, a munition fuzewell is torqued into the aft end of a munition. The fuzewell is hollow and has an inner and an outer surface. The hollow fuzewell is configured to release during cook-off. Release is assisted by employing a biased equivalent strength threaded release ring concentric about the fuzewell. The biased equivalent strength threaded release ring has a threaded inner surface and a threaded outer surface. The biased equivalent strength threaded release ring's threaded inner surface threadingly-engages with threads on the fuzewell's outer surface. A munition case is concentric about the biased equivalent strength threaded release ring.
